Product Description
The 17-70mm F/2.8 Di III-A2 VC RXD (Model B070) is a fast-aperture everyday zoom lens for Sony E-Mount and FUJIFILM X-Mount APS-C mirrorless cameras. Fast, sharp, quiet, and small—this new APS-C zoom lens is extraordinarily versatile and perfect for everyday photography. The lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it’s the world's first 17-70mm F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The 17-70mm includes TAMRON's proprietary VC (Vibration Compensation). When shooting video, by leveraging AI technology, image stabilization performs automatically to best compensate for different shooting situations. Designed specifically for use with APS-C mirrorless cameras, the lens is light weight and compact, even with VC. Its small size and versatility make it a great choice for outdoor, travel and vacation photography, where compact camera bags are preferred, and of course for daily use. The lens is equipped with TAMRON’s RXD (Rapid eXtra-silent stepping Drive) AF drive system, a high-speed, precision stepping motor unit with well controlled motor sound. Additionally, photographers / users can take advantage of a close working distance. It features an MOD (Minimum Object Distance) of 07.5" at the wide-angle end and 15.4" at the telephoto end. It also incorporates a wide variety of other features, including Moisture-Resistant Construction and Fluorine Coating for added durability. In your everyday life and on your trips to distant places, this lens captures all the excitement and discoveries with the finest possible detail.
World’s first fast-aperture standard zoom lens for APS-C mirrorless cameras with the focal length range of 17-70mm (4.1x zoom ratio)
The Model B070 has a focal length range of 17-70mm, equivalent to 25.5-105mm on full-frame cameras. It is the first F2.8 fast-aperture zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.
Outstanding optical performance
The optical construction of the 17-70mm F2.8 features 16 elements in 12 groups. Two GM (Glass Molded Aspherical) and one hybrid aspherical lens elements are precisely arranged to maintain high-resolution performance from edge to edge.
VC mechanism optimized for both still images and video shooting
The 17-70mm F2.8 features TAMRON's proprietary VC mechanism. Additional sophisticated algorithms optimized for this model and a dedicated, independently operating MPU (Micro Processor Unit) all combine to superbly compensate for vibration. This feature is available when the lens is used with cameras with or without in-body image stabilization. When shooting video, by leveraging AI technology, image stabilization performs automatically to best compensate for different shooting situations.
Exceptionally quiet RXD stepping motor
The 17-70mm F2.8 incorporates TAMRON's proprietary RXD stepping motor. Remarkably quiet, the lens facilitates photography and videography in conditions that require silence. Supporting stress-free focusing from the wide-angle to the telephoto end of the zoom range, RXD technology enables the camera's focus tracking of moving objects to perform superbly.
Suppresses focus breathing
The 17-70mm F2.8 has minimal focus breathing, an undesirable phenomenon in which the angle of view changes depending on the focusing distance during videography. By counteracting focus breathing, the 17-70mm F2.8 empowers users' expression of their creative intentions to the fullest degree.
Close focusing MOD is just 7.5” at wide-angle end
A highly portable compact design
Moisture-Resistant Construction and Fluorine Coating provide extra protection
